With the permission, I tried to replace the tag texcode with context to get 
source and result.

context mode=mkiv source=yes text=Gives:
...
/context

Unfortunately, the result doesn't appear.

So, what to do to make the example work?

Will it work automatically once the Ctx/MP engine updates on wiki?

Best regards,

Lukas

The code is MkIV only and the wiki uses MkII.

 So, what to do to make the example work?

Find someone who has time to implement and administrate a working
MkIV wiki solution.

 Will it work automatically once the Ctx/MP engine updates on wiki?

*If* the engine gets updated someday, it will probably work, yes.

ok, can you add this to cont-new.mkiv (after \unprotect):

\def\m_meta_colo_initializations{%
vardef OverlayLineColor=\MPcolor{\overlaylinecolor} enddef;
vardef OverlayColor=\MPcolor{\overlaycolor} enddef;
}

I have that in my local experimental code. It has to do with the fact 
that mp's color spaces are not compatible with each other. As I've used 
that patch for quite a while now I could probably move it to the core.


Maybe more users can test this.

Since you use it for a while it seems to work ⇒ into the core

\stopMPcode

Serif

\startMPenvironment
\ss
\stopMPenvironment

A better alternative would to define

\setupMPtext
 [

  color=...,
  setups=...,

that can be used to set the style for metapost text.


this is ok for me, but then we mighe as well drop \startMPenviroment 
(and someone has to wikify that then)

As we already have instances, I've extended that mechanism, so one can say:

\setupMPinstance

The advantage is that you can have multiple instances in parallel.

Please don't rely on my answer since I haven't been following the
development as closely as I used to in past.

But my guess is that the argument goes into the opposite way. I past
(and still in MKII) one *had to* set up fonts twice - once for the
main document and once for MetaPost since MetaPost did its own
processing of labels and MetaPost didn't see the ConTeXt font setups.
So it was difficult to convince MetaPost to use the same font.

Now (as Aditya explained) metapost automatically inherits font setups
from the main document and it might be that nobody ever thought of /
requested / needed to have a special setup for using different font
for MetaPost labels.

I can think of many workarounds to this, but I agree that there is a
valid reason why
\startMPenvironment
(or some other command) should be able to change the font inside
metapost labels only.

[NTG-context] Font for MetaPost graphics

2012-05-02 Thread Marco
The wiki claims setting up an MPenvironment is enough to change the
font in MetaPost graphics:

\startMPenvironment%[global]
\switchtobodyfont [sans]
\stopMPenvironment

\starttext
This should be serif.

\startMPcode
draw textext(This should be in sans.);
\stopMPcode
\stoptext

However, this has no effect. All text is in default serif font. If
[global] is provided, all text is in sans font. I am aware of a
similar issue in a thread last year¹, but the solution didn't really
address the problem. textext(\sans This should be sans.) works
here, but the point is that the MPenvironment fails. Why is that?

Metapost now runs as a library. All the text is first typeset by ConTeXt 
and metapost only knows the bounding box of the labels.


You can try (untested):

\starttext

This is serif

\switchtobodyfont[sans]
\startMPcode
draw textext(This should be sans);
\stopMPcode

\stoptext

This works, of course. However it continues with sans font even
after \stopMPcode. This is better (but clumsy):

\start
\switchtobodyfont[sans]
\startMPcode
draw textext(This should be sans);
\stopMPcode
\stop
Here serif again.

The text in Metapost adapts to the text set in ConTeXt. But the font
setup should *only* be set for MetaPost, not regular text.

Does that mean, that MPenvironment is deprecated and does not work
